Unsp traum nondisp spondylolysis of 2nd cervcal vert, 7thG

This code describes a follow-up encounter for a patient experiencing delayed healing of a fracture in the second cervical vertebra (C2) that resulted in an unspecified, non-displaced traumatic spondylolisthesis. Spondylolisthesis refers to the anterior displacement of one vertebra over another.

Use this code for subsequent encounters when a patient is receiving ongoing care for a C2 traumatic spondylolisthesis that is not healing as expected. Documentation should clearly indicate delayed healing of the fracture and specify that the spondylolisthesis is non-displaced and traumatic in origin.

• Ensure documentation explicitly states "delayed healing" for the fracture component.
• Verify the spondylolisthesis is traumatic and non-displaced; displaced spondylolisthesis codes are distinct.
• This code is for subsequent encounters; initial encounters for the same condition would use a different seventh character.
